Hello,
Thanks for answering.
  But I have tried to use try...except block but it did'nt work.
  problem is that, the context help file itself generate that message, and this 
comes to my parent window,,,,,i wan to catch this message and avoid it from 
appearing?
    or Is there any way by which i can check whether my help file contains 
helpcontext or not?
    Please respond.
    Thanks.

Hi,
I am using
Application.HelpContext(helpcontext);
But when helpcontext is not available in helpfile then it gives a 
error.
Windows Help:
The Topic does'nt exist.COntact your application vendor for an 
updated helpfile(129).

Now I need to avoid these message dialog for display in application 
and show another help page which is set in case when helpcontext is not 
available.

Please help.
